title: Transgastric endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) in patients with esophageal narrowing using the ultrasonic bronchovideoscope.
abstract: Endobronchial ultrasound-guided fine needle aspiration (EBUS-FNA) is emerging as a critical technology in the evaluation of mediastinal lesions and is increasingly regarded as complementary to endoscopic ultrasound (EUS) in this arena. This complementary role may extend into the abdomen in cases where esophageal strictures prevent the passage of the echoendoscope. The objective of the study was to characterize the uses of EBUS-FNA in the evaluation of gastrointestinal lesions in patients with esophageal narrowing. The study design was a single-center case series. The setting was in a tertiary referral center. Four patients underwent EBUS-FNA to evaluate gastrointestinal lesions; esophageal strictures prevented EUS passage in three, the fourth patient did not tolerate transbronchial EBUS but had abdominal lesions within reach of the EBUS scope. EBUS was used to evaluate the liver, adrenal gland, a retroperitoneal mass, and a celiac axis lymph node. EBUS-FNA has greater potential to evaluate abdominal lesions than has been previously recognized. The EBUS scope represents a safe and readily available technology to evaluate patients with esophageal strictures. Interventional endoscopists should be exposed to this modality.
